It also make some adjustment in bridge sysfs so that we can implement this easily. I've done some tests on this patchset, like: [br_sysfs] 1. change all the attribute values of br or brif: $ echo $value > /sys/class/net/br0/bridge/{*} $ echo $value > /sys/class/net/br0/brif/eth1/{*} 2. meanwhile, on another terminal to observe the msg: $ bridge monitor [br_ioctl] 1. in bridge-utils package, do some changes in br_set, let brctl command use ioctl to set attribute: if ((ret = set_sysfs(path, value)) < 0) { --> if (1) { $ brctl set* 2. meanwhile, on another terminal to observe the msg: $ bridge monitor This test covers all the attributes that brctl and sysfs support to set.
